Taxes designed to reduce damage to the environment by cutting emissions of products such as NO_x or CO₂. Emission taxes can be used as an alternative to, or a supplement for, quantitative controls on emissions. The arguments for using taxes are that they induce reductions in emissions where this can be achieved at least cost, and that they give an incentive to reduce emissions further even when they already comply with quantitative standards.
